Worth knowing before you choose

Kiro - worth knowing

Free includes 50 credits that reset monthly; sign-in is required.
Plan credits reset monthly and do not roll over. Add-on packs cost USD 5-100 at USD 0.04/credit and expire after 12 months.
Model multipliers affect credit use; Sonnet 4.6 is shown at 1.3x Auto. Enterprise overage is USD 0.04/credit and off by default.
Paid plans are available on the social-login/AWS Builder ID path with a billing address in a supported place. Enterprise billing follows AWS profile regions.
Model availability may differ by region and provider. iOS access is TestFlight early access, not a general App Store release.

Replit (Replit Agent) - worth knowing

Not listed on the pages we checked; preserved.
Replit's docs describe a Starter plan; the pricing page shows no Free card.
Plan names resolved 2026-10-27 via docs.replit.com/help/pricing-and-plans and replit.com/blog/pro-plan (2026-02-24): $20/$18 tier = Core, $100/$90 tier = Pro (former Teams sunset, members auto-upgraded).
Core is $18/month billed annually on the pricing page; the docs state $204 per year (about $17/month).
CORRECTION 2026-10-27 (official pricing FAQ): added the Free Mode allowance model (5-hour resets, weekly limits) and effort-based paid overage incl. billable Plan-mode reasoning, add-on credit packs, and the explicit no-free-trial / Starter-free-without-time-limit distinction.
Agent modes: Economy and Power on all plans; Pro/Enterprise add Turbo.
Vendor honesty quote on pricing page: 'Replit Agent is powered by large language models.
While it can produce powerful results, its behavior is probabilistic - meaning it may occasionally make mistakes.' Web (replit.com); Desktop App: native for Windows, Mac, and Linux (Debian-based distributions); Mobile App: iOS 18+ (iPhone/iPad; also runs on macOS Tahoe Macs and paired Apple Watch) and Android.
Note: in-app iOS usage-based billing add is US-only per docs (payment nuance, not an availability statement).
